I have added blood and bone with a NPK of 10-4-0.2. I added about half the recommended amount (two handfuls per sq metre). I also have 60 litres of compost down for each plant.
Now I want to add seabird/bat guano in liquid form to the soil because the phosphorus from the bone meal won't be available for a few months when my plants will be almost finished, so I need a fast release fertilizer phosphorus source like guano liquid.
The guano liquid has a NPK of 10-10-2.
The blood & bone and guano liquid will have a combined NPK of 20-14-2.2. If you take into consideration the phosphorus will not be available for a few months, that deducts it to a NPK of 20-10-2.2. Now if you factor in the NPK of the compost 2-1-1 (Guessing) that leaves us with a NPK of 22-11-3.2. Likewise, if you factor in that I only gave the plants half recommended amount of Blood & bone, that leaves us with a NPK of 17-11-3.2, I think?, please correct me if my calculations are wrong. Anyway, my question is: Will this be too much nitrogen for the plants to handle....NPK: 17-11-3.2
